Swamp Hibiscus

A: Dinner plate hibiscus refers to swamp hibiscus, Hibiscus moscheutos. Some gardeners call it swamp mallow or rose mallow. It gets its name from the flower size: six to eight inches across. The Disco Belle series is common in nurseries, along with ‘Lady Baltimore’, ‘Lord Baltimore’ and ‘Luna’. The stems die back in winter but sprout vigorously each spring.
